Materials Testing in Hydrogen

November 30, 2021
Author(s)
Matthew Connolly, May Ling Martin, Damian Lauria, Peter Bradley, Zack Buck, Andrew Slifka, Robert L. Amaro

Opportunities in electrically tunable 2D materials beyond graphene: Recent progress and future outlook

November 30, 2021
Author(s)
Tom Vincent, Jiayun liang, simrjit singh, eli castanon, xiaotian zhang, deep jariwala, olga kazakova, zakaria al-balushi, Amber McCreary
The interest in two-dimensional and layered materials continues to expand, driven by the compelling properties of individual atomic layers that can be stacked and/or twisted into synthetic heterostructures. The plethora of electronic properties as well as

Magnetic Structure Determination of High-Moment Rate-Earth-Based Laminates

November 29, 2021
Author(s)
D. Potashnikov, E. Caspi, A. Pesach, Q. Tao, J. Rosen, D. Sheptyakov, Hayden Evans, C. Ritter, Z. Salman, P. Bonfa, T. Ouisse, M. Barbier, O. Rivin, A. Keren
We report μSR on the 2D rare earth based parent magnets (Mo 2/3RE 1/3) 2AlC with RE = Nd, Gd, Tb, Dy, Ho and Er, and neutron diffraction on the series with RE ≠ Gd (a neutron absorber). By crossing information between the two techniques, we determine the

Sintered powder oxidation variation as a function of build height for titanium alloy produced by electron beam powder-bed fusion

November 26, 2021
Author(s)
Nicholas Derimow, Alejandro Romero, Aldo Rubio, Cesar Terrazas, Francisco Medina, Ryan Wicker, Nik Hrabe
It is well-established that titanium alloy (Ti-6Al-4V) powder oxidizes during electron beam powder-bed fusion (PBF-EB) due to the high background temperatures resulting from layer preheating and sintering of the powder bed before melting. However, it is

Imaging of Magnetic Excitations in Nanostructures with Microwave Near-Field Microscopy

November 25, 2021
Author(s)
Samuel Berweger, Robert Tyrrell-Ead, Houchen Chang, Mingzhong Wu, Hong Tang, Hans Nembach, Karl Stupic, Stephen E. Russek, Thomas Mitchell (Mitch) Wallis, Pavel Kabos
We present images of spin-wave excitations in a patterned yttrium iron garnet (YIG) thin film obtained by use of near-field microwave microscopy, which can achieve spatial resolution as high as 50 nm. Visualization of magnetic excitations is an enticing

Uncertainty Prediction for Machine Learning Models of Material Properties

November 23, 2021
Author(s)
Francesca Tavazza, Brian DeCost, Kamal Choudhary
Uncertainty quantification in artificial intelligence (AI)-based predictions of material properties is of immense importance for the success and reliability of AI applications in materials science. While confidence intervals are commonly reported for

Activation of Mechanophores in a Thermoset Matrix by Instrumented Scratch

November 17, 2021
Author(s)
Chelsea S. Davis, Jeremiah Woodcock, Ryan Beams, Mitchell Rencheck, Muzhou Wang, Stephan J. Stranick, Aaron M. Forster, Jeffrey Gilman
Scratches in polymer coatings and barrier layers negatively impact optical properties (haze, light transmission, etc.), initiate routes of degradation or corrosion (moisture permeability), and nucleate delamination of the coating. Detecting scratches in

Chiral Spin Bobbers in Exchange-Coupled Hard-Soft Magnetic Bilayers

November 17, 2021
Author(s)
X. H. Zhang, T. R. Gao, L. Fang, S. Fackler, Julie Borchers, Brian Kirby, Brian B. Maranville, S. E. Lofland, A. T. N'Diaye, E. Arenholz, A. Ullah, J. Cui, R. Skomski, Ichiro Takeuchi
The spin structure of exchange-coupled MnBi:Co-Fe bilayers is investigated by X-ray magnetic circular dichroism (XMCD), polarized neutron reflectometry (PNR), and micromagnetic simu-lations. The purpose of the present research is two-fold. First, the
